  The present invention provides a method for the production of oligosaccharides by the fermentation of dextran-sucrase-producing microorganisms with sucrose and maltose. The disclosed process allows for the control of the final composition of the isomaltooligosaccharides by adjustments to pH and the initial ratio of sucrose to maltose.

  Nucleic acid sequences of truncated or mutated alternansucrases, vectors containing these nucleic acids sequences, host cells transformed with the nucleic acid sequences encoding truncated or mutated alternansucrases are provided. Furthermore, a process to recombinantly alternansucrase with a high level of expression, while retaining the enzymatic activity is described.
